To all whom it may] concern. i

lie it known thatJ MAX KAMAN, a cltiaen of the United States,residinga-t Syracuse,

in the county of Onondaga and State of New York, have invented certainnew and useful.'

improvements in Radiators for itutomoif ratus known to Sii als

biles, ot' which the following is a speciiication. I

This invention relates to improvements in radiators, oi' the classemployed for cooling the Water which protects the cylinders ofautomobile motors, and has for its object to provide a novel, simple andeffective water cooler, wherein a greater radiating surface is providedfor a given quantity of water, thereby more readily and more quicklycooling 'the water, than under any other appa- And a further object isto prdvide 'a radiator of the class, which is sectional, and whereineac-h section is capable otiloeing,r applied, removed or replacedwithout disturbing the other sections.

The various features, as Well as, the `parts of the invention will be`anderstood from the detailed description-which follows, whereinreference is made to the accompanying drawings, in which- FigureV 1 is afront elevation of the corn# plete radiator. Fig. 2 'is afhorizontalsection taken on line 2-@2 ci' Fig, 1. Fig. 3 is an enlarged verticalsectiomtaken on Aline 3 3 of Fig. 2. Fig, et is an enlarged pentralvertical cross-section on line et'A Fig. 1. Fig. 5 is a rear sideelevation of the complete device. Fig, 6 is an isometric view, showingthe construction and arrangement of the radiating parts; also showingthe-method of applying the same tothe frame.'

Similar characters of reference are assigned to corresponding partsthroughout the several views.

The drawings illustrate one formof my improved radiator, in which 2represents a hollow frame or body, having relatively large front andrearopenings' and 4, which correspond in location, size and shape.

5 represents a'lling spout or neck which is disposed atthe top of thebod 2, by means of which the'water for coo ing the motor-cylinders (notshown) is supplied. The hot water is carried from the motor to the topportion ofthe radiator by means of l I `a tube or pipe 6. i After theWater is cooled it is carried beck to the motor by a pipe 7, which drawsthe vwaterfroim near thepbottom Patented Ang. 1G, lll.;

application liled iarch 8., 19152. Serial No. 252,855 v of the radiator,The cooling of the water is accomplished by means ot a ser1es of tubesor fines, which are preferably square and grouped-'in similar detachablesections, as 8, 56

9, 10 and 11, each of which consists of simi-V vlar front and 'hackplates or heads 12 and 13,. and. a number ot the tubes l5, which arepreferably horizontally disposed.` :The plates 12 and 13 'have arelatively large num' 55 ber of coinciding perforations 14,-in whichvthe tubes 15 :are inserted, for,p1j0viding:as

many normallyv open lues. through whichi the air passes during thetravel ofthe carga." The tubes' 15 of each of 'the sections 'are 70spaced equi-distantly, .preferably in v vertical 7j and horizontal rows,as shown, andthe tubes are preferably held by the plates 12 and 13 so asto provide clear spaces 15 of one-sixi teenth to one-eighth lof an inchbetween the` .15. adjacent tubes, which spaces lare filled `with the hotwater as it gravitates' fromfthe topv if' to the bottomef the tank 2.The several. sections 8, 9, 10 and 11`When placed in' the framesubstantially close orll the central .'30 openings 3 and 4, and togethercomprise butA a single radiating field, as there are no barriers orpartitions between the ilues of the adjacent sections. Thewater,"iiihether en tering the radiator ,through the 'lling tube 85;?"

5, or the pipe 6, falls upon the topmost tier of thel radiating fines15, of the section 8, and thence circulates or Hows around and betweenall of the lines of the severa'isec-'f tions, unt'il it finally reachesthe free or clear in, space (2 in the bottom of the tank, from" which itdischarges through theV pipel 7,-; rlhe correspondingplates'12 and 13 ofthe. several sections of the radiator,`wl1en the latter are placed inthe frame 2, preferably sa aline with each otherland-also with the freelateral edges of the frame openings-3 and/1, To render the jointsbetweenthe sections, as well as between tlfe ends of the section plates 12 and1S and the rame'- 2 water 10e tight, eac-i1 of said points ispreferably` covered with strips otthinmetal 16 and 17,

' which are preferably soldered in place.

To disconnect one or'more ofthe radiating sections for repairs, thelstrips 16 and; 17. 10s may be readily and quickly removed from the frontand back, by the use of a common solderingiron, after-which the sectionsmay be withdrawn, as shown by, dotted lines in i Fig. l. v l 11,@

The .tank or body 2l is protected by a band-lke casing orshield 18,which surrounds the lateral edges and also partially crei-laps and givesa linished appearance vto the top and the sides of the front of theradiator.

The top of the casing 18 is provided with v a tubular part 22, whichserves as a shield for the filling tube 5, and 28 represents a screw-cap which closes the part 22, and also the mouth of the tube 5, by meansof a balllike part 23". The casing or jacket 18 is detachably secured toan angular metal parth by bolts 20, and the part 19y is preferably to'obviate the necessity of frequent replenishing of the cooling system.

llt/ly improved radiator is extremely simple, and owing to the numberand close arrangement ofthe lues 15, it is capable of quickly andeffectively cooling the water it receives from the motor cylinders.

The provision of a large number of radiating tubes 15 which are arrangedto divide the body of the hot water into relatively thin sheets orcolumns, alords a. greater amount of radiating surface, withoutoccupying'any more space, than any of the older styles of radiators,known to me. find furthermore, the grouping or arranging of theradiating tubes into sectionsof convenient size, which'are readilydetachable in case of leakage or injury to any of the' tubes, is anessentially. novel feature which enhances the value of my improvement.vn p Having tlius described my invention, what I claim as new and desireto secure by Letters Patent, is-`- In a sectional radiator, thecombination of a plurality. of sections, each section comprising spacedfront and back plates, said plates having coinciding perfor-ations, anda series of tubes spanning the space between said plates, the ends ofthe tubes beingdisposed in the corresponding perfor-ations and' beingflush with the outer faces vof said plates, the respective walls of the`tubes being spaced equi-distantly from the walls of the adjacent tubes,whereby to provide vertical and horizontal columns of Water of the samethickness surrounding each tube, the

`said radiator sections being disposed horizontally, and the front andback .plates of the respective sections projecting above and below thewalls of the tubes of therespective sections and adapted to be connectedto one another, whereby to provide a water space of substantial areabetween the tubes of the adjacent sections.

ln testimony whereof I ailix my signature in presence of two witnesscs.`
